Letters Patent No. 108,928, dated November 1, 1870.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that I, Funnels 13. Mouse, ofPlantsville, in the county of Hartford and State of Connecticut, haveinvented a new Improvement in Shaft- Irons for Carriages; and I dohereby declare the ihllowing, when taken in connection with theaccompanying drawing and the letters of reference marked thereon, to hea full, clear, and exact description of the same, and which said drawingconstitutes part of this specification, and represents in- Figure 1, aside view of the shaft-iron, as attached to the shaft;

Figure 2, a perspective view of the article as propared for the tradeready for use; and in Figure 3, a transverse section on line a: a; offig. 1, illustrating the operation of the invention.

This invention relates to an improvement in the article of manufactureknown to the trade as shaftirons for carriages, that is, the eye bywhich the shafts are attached to the shackle. These are formed intoshape, and to thenrthe shafts are fitted. The-end of the shaft at theeye being worked down quite narrow, is liable to split, in consequenceof the belt which passes through it to secure the end of the shaft tothe iron.

Another difiiculty is the liability of the iron to break at the pointwhere this first bolt passes through, for the iron at that point isnearly perpendicular, so that the draft or strain is nearly squareacross the iron.

The object of my invention is to construct the iron so as to alford'aprotection to that portion of the shaft, also to strengthen the iron atthe first bolt; .and

My invention consists in forming ears upon each side of the iron,extending up, so as to he closed over onto the shaft.

A is the eye, and

B, the shank of the iron, of the usual form.

Onto the top of the shank the shaft 0 is fitted, and secured by a bolt,D, passing through both the shaft and iron. The strain, consequent uponthe use of the shafts, frequently splits the shafts at that point.

To avoid this, I form upon each side of the iron an ear, P, as seen infigs. 1 and 2, which is done in the process of forging, and are leftperpendicular, as seen in fig. 2.

The consumer, after having fitted the shaft 0, strikes the ears P downonto the shaft, as seen in fig. 3, the ears being of sufficient strengthto sustain the shaft against the lateral strain and prevent thesplitting of the shaft, and, at the same time, strengthen the iron atthe same point, which is where the iron is most liable to break.

I claim as my invention- As an improved article of manufacture,shaft-irons having the ears P P formed thereon, and so as to he closeddown onto the. shaft, as herein set fortl 4 1*. B. MO SE. \Vitnesses:
